3 Claims.

The present invention relates to new bisquatemary ammonium compounds which can be represented by the following general formula:

x R! R1 x (I) wherein R and R1 represent lower alkyl radicals; X represents a halogen, e. g., chlorine, bromine or iodine; Y represents a nitrol rad cal, and A represents (CHQ)I (where r=2 and 3).

The new compounds as represented by the above Formula I are useful as curariform compounds.

In general, the new compounds can be prepared by quaternizing iii-tertiary amines oi the following formula:

with a benzyl halide of the following formula:

Y- CH x R, R1, A, X, and Y having the same meaning as hereinabove assigned thereto.

Preparation of a di-tertiary amine which is new is illustrated by the following example:

EXAMPLE A 1,4-bis(' -diethylamimpropomyi benzene (Cl. EGO-567.6)

then evaporated. The crude 1,4-bisby-diethylaminopropoxy) benzene thus obtained was distilled in vacuo, and the fraction boiling at 161- 179 C. and 0.1 mm. mercury was dissolved in acetone. To the solution 63 grams of picric acid were added and the dipicrate precipitated. It melted at 159 C. The free base was obtained by treating the dipicrate with an excess 01' a saturated solution of lithium hydroxide, and the resulting mixture was extracted with ether. The ether extract was washed with water, dried over anhydrous sodium sulfate, and the ether evaporated. The residual base was then distilled in vacuo and boiled at 169 C. and 0.08 mm. mercury pressure.

The following examples will serve to illustrate the preparation of the new bis-quaternary ammonium compounds represented by the hereinabove given Formula 1:

EXAMPLE 1 (p-phenylenedioxy) bis diethyl(p-nitrobenzyl) prom/l ammonium bromide] EXAMPLE 2 s,p'- (p-phenylenediozy) bis [triethyHp-nitrobenzul) ammonium bromide] 6 grams of 1,4-bis(fl-diethylaminoethoxyl-benzene were dissolved in cc. of benzene and 8.6 grams of p-nitrobenzyl bromide in 125 cc. of benzene were added. The mixture was refluxed for 1 hour and then allowed to stand at 25 C. for 18 hours. The crystals which formed were separated and recrystallized from methanol. The fl.fl'- (p phenylenedioxy)bisitriethyl(p nitrobenzyliammonium bromide] melted at -197 C. with decomposition.
